4. Cell Membrane
The cell membrane is a thin, flexible barrier that surrounds every cell. It protects the cell's contents and regulates the passage of materials into and out of the cell. The cell membrane is composed of a lipid bilayer, which is a double layer of lipid molecules. Lipid molecules are composed of a hydrophilic (water-loving) head and a hydrophobic (water-hating) tail. The hydrophilic heads of the lipid molecules face outward, toward the aqueous environment inside and outside the cell. The hydrophobic tails of the lipid molecules face inward, away from the aqueous environment.
